The nature of light is a focus of Thomas Hobbes’s natural philosophical project. Hobbes’s explanation of the light of lucid bodies differs across his works, from dilation and contraction in Elements of Law to simple circular motions in De corpore. However, Hobbes consistently explains perceived light by positing that bodily resistance generates the phantasm of light. In Letters I.XIX–XX of Philosophical Letters, fellow materialist Margaret Cavendish attacks the Hobbesian understanding of both lux and lumen by claiming that Hobbes has illicitly (...) made abstractions from matter. In this paper, I argue that Cavendish’s criticisms rely on an incorrect understanding of the nature of Hobbesian geometry and the role it plays in Hobbes’s natural philosophy. Rather than understanding geometry as wholly abstract, Hobbes attempts to ground geometry in different ways of considering bodies and their motions. Furthermore, Hobbes’s own criticisms of abstraction suggest that he would share many of the worries she raises but deny that he falls prey to them. (shrink)

Margaret Cavendish was a philosopher and writer active in mid-seventeenth century England. She is important not just as one of the first women active in philosophy in early modern age but as the expounder of an original scientific theory based on vitalism and materialism, by which she rejected the mechanical philosophy of Descartes and Hobbes and the experimental philosophy of Boyle and Hooke. Also, while not developing a theory of gender equality, she envisaged a form of emancipation of women based (...) on intellectual activity as a way to social recognition and to the exercise of influence on society and politics.

Elisabeth was the first of Descartes' interlocutors to press concerns about mind-body union and interaction, and the only one to receive a detailed reply, unsatisfactory though she found it. Descartes took her tentative proposal `to concede matter and extension to the soul' for a confused version of his own view: `that is nothing but to conceive it united to the body. Contemporary commentators take Elisabeth for a materialist or at least a critic of dualism. I read her instead as a (...) dualist of a different variety from Descartes: a forerunner of twenty-first century naturalistic dualism which calls for empirical investigation of the psychological and its posits to be taken just as seriously as physics and its posits. -/- I argue that Elisabeth, a keen scholar of mechanistic physics, objected not to substance dualism per se but to the residual Scholasticism of Descartes' account of mind-body causality and his dogmatism about principal attributes. She queried Descartes' categorisation of the `action' of thought as mind's principal attribute, and his identification of it with the merely negative property of immateriality, holding instead that further philosophical and empirical investigation into the nature of the mind is necessary. I problematise the materialist interpretation of Elisabeth with reference to later letters where she dismissed the materialist Objections of Hobbes and Gassendi and continued to urge further clarifications to Cartesian dualism. I explore Elisabeth's contrasting of statements of mechanistic physics with statements about thought, and her call for further investigation into the properties of the mind, and argue they mark her out as a forerunner of contemporary naturalistic dualism which proposes substance dualism as a best interpretation of recent psychology and of the difference in logical form between current physics and current psychology.

ABSTRACTIn this paper, I explore Margaret Cavendish’s engagement with mid-seventeenth-century debates on spirits and spiritual activity in the world, especially the problems of incorporeal substance and magnetism. I argue that between 1664 and 1668, Cavendish developed an increasingly robust form of materialism in response to the deficiencies which she identified in alternative philosophical systems – principally mechanical philosophy and vitalism. This was an intriguing direction of travel, given the intensification in attacks on the supposedly atheistic materialism of Hobbes. While some (...) scholars claim that Cavendish’s views were not formed out of extensive engagement with contemporary thinkers, I suggest that, on the contrary, Cavendish engaged very closely with the views of More, Hobbes and others – including the vitalist thinker Johannes Baptista van Helmont and the mechanical philosopher Henry Power – on the subject of spirits and...

Perception plays a central and wide-ranging role in the philosophy of Margaret Cavendish. In this paper, I argue that Cavendish holds a naïve realist theory of perception. The case draws on what Cavendish has to say about perceptual presentation, the role of sympathy in experience, the natures of hallucination and of illusion, and the individuation of kinds. While Cavendish takes perception to have representational content, I explain how this is consistent with naïve realism. In closing, I address challenges to the (...) interpretation, one of which turns on whether Cavendish allows for action at a distance. I argue that she does. (shrink)

In this paper, I offer a new interpretation of Margaret Cavendish’s remarks on beauty. According to it, Cavendish takes beauty to be a real, response-independent quality of objects. In this sense, Cavendish is an aesthetic realist. This position, which remains constant throughout her philosophical writings, contrasts with the non-realist views that were soon after to dominate philosophical reflections on matters of taste in the early modern period. It also, I argue, contrasts with the realism of Cavendish’s contemporary, Henry More. While (...) there are passages in Cavendish’s work that might seem to count against my reading—specifically, passages on disagreement in aesthetic judgement, on the power of beauty to elicit the passions, and on our inability to specify the nature of beauty—I show that, when situated against the background of Cavendish’s broader metaphysical and epistemological views, those passages in fact support the realist interpretation.

Throughout her philosophical writing, Margaret Cavendish is clear in stating that colours are real; they are not mere mind-dependent qualities that exist only in the mind of perceivers. This puts her at odds with other seventeenthcentury thinkers such as Galileo and Descartes who endorsed what would come to be known as the ‘primary-secondary quality distinction’. Cavendish’s argument for this view is premised on two claims. First, that colourless objects are inconceivable. Second, that if an object is inconceivable then it could (...) not possibly exist in nature. My aim in this paper is to explain why Cavendish accepts both premises of this argument. However, the repercussions of this paper go much further than just explaining why she thinks colourless objects cannot exist in nature and the upshots are twofold. First, it provides new insights into the fundamental role that perception plays in Cavendish’s metaphysics. While Cavendish’s view that all of nature perceives is well-established, I show that Cavendish is also committed to the view that all of nature is perceivable. Second, it provides the first in-depth discussion of Cavendish’s modal epistemology and her reasons for thinking that inconceivability entails impossibility (in nature). (shrink)

This paper explores Cavendish’s argument for what she calls “animate matter.” Her commitment to the ubiquity of animate matter, styled “Cavendish’s animism,” is presented as the conclusion of an inference to the best explanation of nature’s order. The reconstruction of Cavendish’s argument begins with an examination of the relationship between God’s creation of our world and the order produced through nature’s wise governance of her parts. Cavendish’s materialism and anti-atomism are presented as ingredients in her final account of God’s ordering (...) of the world by making it a self-moving whole. On the present account of Cavendish’s metaphysics, this self-moving whole then freely produces the regular motions that constitute its ordering of itself, as a distinct ordering beyond God’s initial act of creating our world. The depth of Cavendish’s commitment to the animistic elements of her materialism—or in other words, the extent to which her system is genuinely animistic—is then considered. (shrink)

This paper pursues a question about the spatial relations between the three types of matter posited in Margaret Cavendish’s metaphysics. It examines the doctrine of complete blending and a distinctive argument against atomism, looking for grounds on which Cavendish can reject the existence of spatial regions composed of only one or two types of matter. It establishes, through that examination, that Cavendish operates with a causal conception of parts of nature and a dynamic notion of division. While the possibility of (...) unmixed spatial regions is found to be consistent with both the doctrine of complete blending and Cavendish’s anti-atomism by themselves, it is finally ruled out by a consideration of her theory of place. In fact, the geometrical question of the spatial relations between types of matter that drives the paper is ultimately exposed as illicitly mathematical from the perspective of Cavendish’s metaphysics.

This paper reconstructs Margaret Cavendish’s theory of the metaphysics of artifacts. It situates her anti-mechanist account of artifactual production and the art-nature distinction against a background of Aristotelian, Scholastic, and mechanist theories. Within this broad context, it considers what Cavendish thinks artisans can actually do, grounding her terminological stipulation that there is no genuine generation in nature in a commitment to natural and artistic production as the mere rearrangement of bodies. Bodies themselves are identified, in a conceptually Ockhamist manner, with (...) their figures, so that the resulting theory of mere rearrangement is Scholastically respectable. The paper also offers literal interpretations, focused narrowly on the philosophical content of her theories of art and artifacts, of her claims that art concerns only “nature’s sporting or playing actions”, that its products are “deformed and defective”, and that they are “at best …mixt or hermaphroditical.".

The empress of Margaret Cavendish’s The Blazing World dismisses pure mathematicians as a waste of her time, and declares of the applied mathematicians that “there [is] neither Truth nor Justice in their Profession”. In Cavendish’s theoretical work, she defends the Empress’ judgments. In this paper, I discuss Cavendish’s arguments against pure and applied mathematics. In Sect. 3, I develop an interpretation of some relevant parts of Cavendish’s metaphysics and epistemology, focusing on her anti-abstractionism and what I call her ’assimilation’ view (...) of knowledge. In Sects. 4 and 5, I use this to develop Cavendish’s critiques of pure and applied mathematics, respectively. These critiques center on the claims that mathematics purports to describe non-beings, that nature is infinitely and irreducibly complex, and, perhaps most originally, that mathematical thinking deforms the subject of representation, not just the object.

This paper provides a systematic reconstruction of Cavendish's general epistemology and a characterization of the fundamental role of that theory in her natural philosophy. After reviewing the outlines of her natural philosophy, I describe her treatment of 'exterior knowledge', i.e. of perception in general and of sense perception in particular. I then describe her treatment of 'interior knowledge', i.e. of self-knowledge and 'conception'. I conclude by drawing out some implications of this reconstruction for our developing understanding of Cavendish's natural philosophy.

In this paper, I develop a new interpretation of the order of nature, its function, and its implications in Margaret Cavendish’s philosophy. According to the infinite balance account, the order of nature consists in a balance among the infinite varieties of nature. That is, for Cavendish, nature contains an infinity of different types of matter: infinite species, shapes, and motions. The potential tumult implicated by such a variety, however, is tempered by the counterbalancing of the different kinds and motions of (...) matter against one another, or what Cavendish calls the “poising” of nature’s actions by their opposites. The infinite balance account of order offers insight into a central notion of Cavendish’s system and bears important implications for other interpretive issues. To wit, the account resolves the standing issue of whether there is genuine disorder in Cavendish’s universe and elucidates the nature of her opposition to atomism. Nevertheless, the interpretation faces an epistemic challenge, insofar as Cavendish appears to deny knowledge of infinity. I argue that, for Cavendish, our knowledge of the order of nature is conceptual and non-empirical, revealing limits to her apparent empiricism. (shrink)

In this paper, I argue that Margaret Cavendish’s account of freedom, and the role of education in freedom, is better able to account for the specifics of women’s lives than are Thomas Hobbes’ accounts of these topics. The differences between the two is grounded in their differing conceptions of the metaphysics of human nature, though the full richness of Cavendish’s approach to women, their minds and their freedom can be appreciated only if we take account of her plays, accepting them (...) as philosophical texts alongside her more standard philosophical treatises.

It has often been noted that Margaret Cavendish discusses God in her writings on natural philosophy far more than one might think she ought to given her explicit claim that a study of God belongs to theology which is to be kept strictly separate from studies in natural philosophy. In this article, I examine one way in which God enters substantially into her natural philosophy, namely the role he plays in her particular version of teleology. I conclude that, while Cavendish (...) has some resources with which to partially alleviate this tension, she is nonetheless left with a significant difficulty. (shrink)

Consider the distinctive qualitative property grass visually appears to have when it visually appears to be green. This property is an example of what I call sensuous color. Whereas early modern mechanists typically argue that bodies are not sensuously colored, Margaret Cavendish (1623–73) disagrees. In cases of veridical perception, she holds that grass is green in precisely the way it visually appears to be. In defense of her realist approach to sensuous colors, Cavendish argues that (i) it is impossible to (...) conceive of colorless bodies, (ii) the very possibility of color experience requires that bodies are sensuously colored, and (iii) the attribution of sensuous colors to bodies provides the best explanation of color constancy. Although some passages might suggest that Cavendish endorses a reductive account of sensuous color, according to which sensuous color reduces to a body's microscopic surface texture (or some other mechanistically respectable property), I argue that she accepts a nonreductive account, on which sensuous color is not thus reducible.

Our modern ideals about liberty were forged in the great political and philosophical debates of the 17th and 18th centuries, but we seldom hear about women's contributions to those debates. This paper examines the ideas of early modern English women – namely Margaret Cavendish, Mary Astell, Mary Overton, ‘Eugenia’, Sarah Chapone and the civil war women petitioners – with respect to the classic political concepts of negative, positive and republican liberty. The author suggests that these writers' woman-centred concerns provide a (...) unique historical perspective on these much-discussed ideals of freedom from external interference, freedom as self-determination and freedom from domination.

Some scholars have argued that Margaret Cavendish was ambivalent about women's roles and capabilities, for she seems sometimes to hold that women are naturally inferior to men, but sometimes that this inferiority is due to inferior education. I argue that attention to Cavendish's natural philosophy can illuminate her views on gender. In section II I consider the implications of Cavendish's natural philosophy for her views on male and female nature, arguing that Cavendish thought that such natures were not fixed. However, (...) I argue that although Cavendish thought women needed to be better educated, and could change if they had such an education, she also thought their education should reinforce the feminine virtues. Section III examines Cavendish's notorious “Preface to the Reader” (from The Worlds Olio), where Cavendish claims that women are naturally inferior in strength and intelligence to men. Section IV addresses another notorious Cavendish text, “Female Orations,” arguing that its message is similar to that of the “Preface to the Reader.” Nonetheless, although Cavendish held conventional views about male and female nature and appropriate gender roles, she also recognized how social institutions could limit women's freedom; section V explores the complexities of Cavendish's critique of one such institution, patriarchal marriage.

Scholarly interest in Margaret Cavendish's philosophical views has steadily increased over the past decade, but her epistemology has received little attention, and no consensus has emerged; Cavendish has been characterized as a skeptic, as a rationalist, as presenting an alternative epistemology to both rationalism and empiricism, and even as presenting no clear theory of knowledge at all. This paper concludes that Cavendish was only a modest skeptic, for she believed that humans can achieve knowledge through sensitive and rational perception as (...) well as through self-knowledge and can form probable opinions through reasoning.

This essay explores an unstudied compendium to Margaret Cavendish’s 1655 Philosophical and Physical Opinions that was composed by the learned physician, plant anatomist, and secretary of the Royal Society, Nehemiah Grew. Despite the growing body of scholarship on Cavendish, minimal attention has been dedicated to her early reception. But studying this compendium provides some fascinating insights into how one of the foremost thinkers of her day read, emended, and manipulated her ideas. I propose that Grew turned to Cavendish’s work when (...) developing his substance theory in the years leading up to the publication of his 1682 The Anatomy of Plants, but that shifting intellectual tides led him to critique her version of material vitalism in his 1701 Cosmologia Sacra. Supported by a transcription of the compendium as an appendix, this article also sheds light on the role that early modern pedagogical techniques and memory tools played in shaping concepts of matter and mind.

Margaret Cavendish is widely known as a materialist. However, since Cavendishian matter is always in motion, “matter” and “motion” are equally important foundational concepts for her natural philosophy. In Philosophical Letters (1664), she takes to task her materialist rival Thomas Hobbes by assaulting his account of accidents in general and his concept of “rest” in particular. In this article, I argue that Cavendish defends her continuous-motion view in two ways: first, she claims that her account avoids seeing accidents as capable (...) of generation and annihilation, which she argues is inconceivable; and second, she contends that according to Hobbes’s own view “rest” is an absurd conception since it cannot be drawn from experience. Beyond its function as a defense, I claim that Cavendish’s focused criticism of “rest” shows that she is a perceptive reader of Hobbes’s natural philosophy, insofar as her criticisms undercut the two a priori principles of Hobbesian physics. Finally, I show how her views developed in more detail in Philosophical and Physical Opinions (1663) and Observations upon Experimental Philosophy ([1666] 2001) avoid the worries she raises for Hobbesian materialism.

This paper discusses the materialist views of Margaret Cavendish, focusing on the relationships between her views and those of two of her contemporaries, Thomas Hobbes and Henry More. It argues for two main claims. First, Cavendish's views sit, often rather neatly, between those of Hobbes and More. She agreed with Hobbes on some issues and More on others, while carving out a distinctive alternative view. Secondly, the exchange between Hobbes, More, and Cavendish illustrates a more general puzzle about just what (...) divided materialists from their opponents. Seemingly straightforward disagreements about whether incorporeal substances exist turn out to be more complex ones in which the nature of those things is disputed at the same time as their existence.

For Margaret Cavendish, every single part of matter has self-knowledge, and almost every part has perceptive knowledge. This paper asks what is at stake for Cavendish in ascribing self-knowing and perceptive properties to matter. Whereas many commentators take perception and self-knowledge to be guides to Cavendish’s epistemology, this paper takes them to be guides to her metaphysics, in that it shows that these categories account for individual specificity and for relationality. A part of matter is a unique individual insofar as (...) it is self-knowing – and it is a part in relation to other parts, and to the whole of matter, insofar as it is a perceptive part. This is so because self-knowledge is purely self-referential and complete, while perceptive knowledge is purely relational. (shrink)

This paper examines the surprisingly central role of sympathetic love within Margaret Cavendish’s philosophy. It shows that such love fulfils a range of metaphysical functions, and highlight an important shift in Cavendish’s account vis-a-vis earlier conceptions: sympathetic love is no longer given an emanative or mechanistic explanation, but is naturalized as an active emotion. It furthers investigate to what extent Cavendish’s account reveals a rift between the realm of nature and the realm of human sociability, and whether this rift really (...) prompts an inward turn, as some interpreters have suggested.
